science say the reef has lost half of its coral cover over the past 27 years. there are multiple causes, including a destructive kind of starfish shown here. we look at what's behind it and what's at stake-- in australia and around the world-- with nancy knowlton, a coral reef biologist and a chair of marine science at the smithsonian national museum of natural history here in washington. welcome. >> thanks. how has all of this coral died off? do we know what's causing it? is it all that... >> it's not all the star fish. the star fish is about 42%. typhoons, big strong storms another 48% and then coral bleaching is the remaining 10% which is caused whenever the water gets too hot. >> ifill: so this is human causedded? >> yes. most of it is human caused. i mean a coral reef naturally goes through cycles of up and down. but it shouldn't be declining by half over course of 27 years. >> ifill: i feel like we have talked before about the declining coral cover. but not... but i'm wondering whether it's now picking up speed or whether this is just a natural deterioration that we should just be
of marine science released a report tuesday saying a number of reeves has gone from 100 to 47 since 1985. experts blame the rapid increase in crown of thornz star fish which eat the coral. they found that ocean warming is a major cause of coral bleaching and prevents the coral from recovering from cyclone damage and they worry that it could halve againy the next decade if current trends continue. >> we believe if we can take action, the crown of thorn star fish, it may leave the reef in a position that can better withstand the climactic impact. >> the great barrier reef extends more than 2,000 kilometers off the coast of northeastern australia and is a world heritage site. >>> a gallery of japanese art has opened at an art museum in melbourne, australia. a ceremony was held on tuesday for the opening of the paulen gander gallery of japanese art named after gandel who donated her collection of japanese art. they performed a japanese ritual to celebrate the opening and the exhibits include a buddhist statue from the 8th to 12th century and a hanging scroll by an 18th century artist. it has
lost over half its coral in just a single generation. >> this trillion institution of marine science says the pace of damages kicking up. cyclones of predatory starfish are the main causes along with: gas shipments and global warming. >> coral reefs provide the breeding ground for countless species of fish. the great barrier reef is no exception. commercial fishing is now mostly banned across much of the area. three 6 cents more than 2,600 kilometers along the us trillion coast. the northern part of the refinements largely intact. it is the southern part scientists are worried about. severe storms are said to have cost nearly 50 percent -- said to have caused nearly 50% of the damage. a further 40% was caused by starfish that feed on the coral. one species, the crown of thorns, has proven especially deadly for the coral cover. >> we believe if we can take action on one of the things we can directly control, the crown of thorns starfish, it may leave the reef in a position where it can better withstand some of the climatic impact spite cyclone and coral bleaching. >> regardless of wha
of marine science says the number of reefs has dropped from 100 to 47. since 1985. the scientists identified two main causes of coral decline. the crown of thorn star fish is growing rapidly in number. the fish feed on the coral. and ocean warming is bleaching the coral. the scientists say this prevents the reef from recovering after cyclone damage. they worn coral cover could halve again by the end of the next decade if current trends continue. >> we believe that if we can take action on one of the things we can directly control, the crown of thorn starfish, it may leave the reef in a position where it can better withstand some of these climatic impacts. >> the reef extends more than 2,000 kilometers off the coast of northeastern australia. >>> officials and locals in india pulled together to pull one endangered species from the mud. they spent ten hours digging an indian rhinoceros from a swamp in the northeastern state. about 2,300 rhinos live in the national park, two-thirds of the world's population of the endangered animal. one of the rhinos strayed from the park after it was hit by fl
the most government funded research to push the boundaries of science and technology so our best innovators and the entrepreneurs could pluck them and start these companies. if you think about that is a formula for success, and education we now -- well, roughly 30% of high school students drop out of high school. we used to lead the world in college graduates coming out of high school. we no longer do that. on infrastructure, according to the american society of civil engineers we are now $2 trillion in deficit in terms of infrastructure. immigration we have a policy to get a great education and then get the hell out of our country. we are fighting on the simplest h-1b issues that are so vital for our future strength. fourth, the rules for incentivizing risk-taking and preventing recklessness. i don't think that we have in any way remedied that the way we want and on the government funded research if it looks like an ekg heading for a heart attack. i don't know if they are relative to what. all i know is in the things that have historically made us great, on each one of those i see us not g
for inviting me. >> hong kong university of science and technology. very much appreciate your thoughts. let's give you a look at what's on the agenda in asia tomorrow. japan central bank begins its two-day policy meeting. the boj is likely to stand pat this time around but may signal more stimulus on the 30th of october. elsewhere, india posed september services pmi following strong numbers in august and cnbc will have an exclusive interview with malaysia's prime minister, so be sure to tune in for that. >>> back over this side of the world, business activity in the eurozone shows no sign of a rebound. the latest composite pmi figures for september fell to the low nest three years. france and spain saw a mild contraction as the country struggled with painful austerity measures. >>> meanwhile, growth in britain's sector services slowed in september. services pmi fell to 52.2 last month down from a reading of 53.7 in august. joining us now discuss is chris williamson, chief economist at market. good to have you onboard. i want to start out with the uk numbers because we've seen some move in t
isn't rocket science. it's just common sense. from td ameritrade. >>> we've heard it all morning long it and still makes us jump. a huge 747 crashing in the dessert, by remote control, all part of the discover channel's new "curiosity" series where a controlled experiment was captured by 40 cameras and sensors to give researchers what happens during a crash atlantaing. >> it airs on discovery channel this sunday night at 9 p.m. two top experts are here with us now, accident investigator dr. tom barth and dr. cindy bir. >> thank you for being with us this morning. we're very excited about this. >> i asked you, dr. bir, earlier, have you ever attempted to do this before and you said you have. this took over four years to plan. why did you want to crash a plane? >> we were -- i was approached by a production company to do this about four years ago. i think tom and i were approached about the same sometime. and was just such an interesting project. i didn't attempt it before, but it was attempted back in '84. and they had lessons learned. we have new technology. so, it was a wonderful opp
and every like to possessors of political science speculating in the abstract about the nature of international politics. you may wonder why it was because of fact the only thing worth talking about was at that point whether we could establish enough confidence between the two of us to risky adventure that opening to china representative for both sides shown that point of view, from a domestic, political point of view. and even though the subject of president nixon to china, was the reason why i came, neither side mentioned it until about 12 hours before. i mention not only to say i believe it should be followed to get your object it straight before you start haggling about details. we had no choice. now every generation and then was a great reform and i cannot think of any other country where you could definitely say that the evolution that we have seen in the last 30 years, depending on the vision of one man, as in the case of no other chinese who had the vision and the courage to move china into the imaginative system and to engage the reform and instituting a market system.
